Abstract

The RATP has carried out a programme of successful experiments on a device for locating the position of mobiles, using the GPS (Global Positioning Service) satellite system. Its accuracy, all things considered, is about 10 m. The system's initial application will be in relation to the bus network (4000 vehicles) for matters of personal security, being able to provide a precise location for a bus in an emergency situation, for bus traffic flow regulation and for passenger information purposes. Brief details are provided of: a) the system architecture; and b) a study to evaluate the accuracy of the system. Brief details of each of the applications are also provided. These include: a) the ORGAS (operational Route Global Assistance System) system; and b) the ALTAIR system, which regulates bus movements and provides a passenger information service.
